Nearly one in ten U.S. adults over the age of 65 are living with a neurocognitive disorder, according to a study conducted by Columbia University researchers in 2022. But what exactly is dementia? 

The Alzheimer’s Association defines dementia as “a general term for loss of memory, language, problem-solving, and other thinking abilities that are severe enough to interfere with daily life.” It’s not a single disease; it can manifest in various forms, with four below being the most prevalent. By understanding and addressing the unique symptoms and progression of each form, we can significantly improve care and personalize our approach for your loved one.

Nearly one in ten U.S. adults over the age of 65 are living with a neurocognitive disorder, according to a study conducted by Columbia University researchers in 2022. But what exactly is dementia? 

The Alzheimer’s Association defines all types of dementia as “a general term for loss of memory, language, problem-solving, and other thinking abilities that are severe enough to interfere with daily life.” It’s not a single disease; it can manifest in various forms, with four below being the most prevalent types of dementia. By understanding and addressing the unique symptoms and progression of each form, we can significantly improve care and personalize our approach for your loved one.

TYPES OF DEMENTIA

The Many Faces of Dementia Explained

Alzheimer’s Disease

Alzheimer’s disease causes approximately 80–90% of types of dementia cases. It occurs when brain cells and their connections begin to degrade and deteriorate. 

Symptoms include:

  • Language difficulties
  • Memory loss
  • Increased confusion 
  • Disorientation
  • Mood swings
  • Decreased motivation

These symptoms intensify over time, with each stage requiring increasingly comprehensive care. The typical progression spans eight to ten years, although this varies from person to person.

Care strategies:

  • Memory aids (sticky notes, digital reminders, daily routines) 
  • A safe, supportive living environment 
  • Regular social interactions

Vascular Dementia

Vascular dementia accounts for 10-20% of neurocognitive disorders and follows a distinctive progression that is often triggered by one or more strokes.

Symptoms include:

  • Problem-solving challenges
  • Slowed thinking
  • Difficulty concentrating
  • Mood fluctuations
    These symptoms may stabilize and then worsen.

Care strategies:

  • Preventing further cerebrovascular damage through a heart-healthy diet, regular exercise, and adherence to medical treatments
  • Cognitive exercises 
  • A structured daily routine

Lewy Body Dementia

Lewy body dementia (LBD) is the third most common type of dementia after vascular, comprising 5-10% of all cases. LBD is caused by an accumulation of protein deposits in the brain.

Symptoms include:

  • Problems with attention and alertness
  • Visual hallucinations
  • Motor impairments 
  • Sleep disturbances

Symptoms of LBD can fluctuate dramatically, posing a challenge for day-to-day management.

Care strategies:

  • Safety parameters like walkers and handrails
  • Handling hallucinations with gentle reassurances and redirection
  • Avoiding direct contradictions of your loved one’s experiences 
  • A soothing bedtime routine and environment

Frontotemporal Dementia

Frontotemporal dementia is caused by nerve cell loss in the brain’s frontal or temporal lobes. Under this type of dementia, symptoms can begin to surface between ages 45 and 65 and tend to progress more rapidly than other types of neurocognitive disorders.

Symptoms include: 

  • Changes in behavior and personality
  • Emotional detachment
  • Language difficulties

Care strategies:

  • Consistent and structured behavioral management techniques
  • Communication aids like picture boards or specialized apps
